CORRUGATED CULVERT.

Specification of Letters Patent. Application led November` 23, 1911.

Patented Mar. 12, 1912. Serial No.' 662,044.

To all whom 'it may concern:

Beit known that I, Gnonon W. WARNER, a citizen of the United States, residing at Topeka, in the county ot' Shawnee and State of Kansas, vhave invented certain new Vand useful Improvements in` Corrugated Cul-l verts; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichit appertains to make and use the saine, reference being had to the accompanying' drawings, and 't the letters and figures of reference marked thereon, which form a part of this specification.

My invention .relates to metal culverts and more particularly to culverts made of corrugated metal pipe; the object' of my invention being to provide an improved joint t'or connecting the separatesections of iwhich theculvert is composed. In order to accomprovided the improved details of' structure hereinafter deaccompanying drawings, wherein -vert"sections before they are united. Fig. II

is a side View of the united sections, showing a fastening strap. Fig. III is a `longitudinal Fig. IV is 'a cross section showing the lmounting of the fastening strap. vFig V is a perspective View of a slightly .modified form of my invention.

Referring more in detail to the parts l designates a section of corrugated culvert, one end of which has its body cut to admit the end of an abutting pipe laterally, the

cut out part preferably comprising slots 9.-2 near the horizontal center of the pipe.

The end of the abutting pipe 3 is uncut, but adapted to'pass through the slots laterally and seat with its lower tom'of the slotted pipe and. its upper portion on the top thereof (Fig. I). Fixedto the i slotted pipe, at the lower edge of the hori- .zontal slots 2', is a laterally directed ear Il,

. which may be either formed from a part of the culvert pipe itself or made from a separate piece and riveted in place. This ear is provided with an aperture 5.

Fixed to the side of pipe 1, at the lower edge of' the slot 2, is a hinge member 6, and hinged to the member 6 1s a semi-circular strap 7, lof slightly greater' diameter than that of the culvert pipe, the freeend of the strap bein provided with an offset ear 8, which is a apted to seat on the ear 4 and has portion on the bot-n an aperture 9 adapted to register with the aperture 5 in the ear Il.

In joining the sectionsLthe uncut end of the pipe 3 is placed through the slots 2-*2 and lowered so that its lower portion will seat on the 'bottom oi' pipe 1 on the inside, and the upper part will rest on top of the first section, the corrugations of each Section nesting with the corrugations of the other, to form a continuous conduit with semi-cylindrical overlapping and interlocked portions.

yith the sections in place, the strap 7 is brought into place to bind the sections together and is bolted or otherwise rigidly secured to thc ear 4, so that the sections are permanently joined, the strap preventing lateral and the nesting corrugations preventing longitudinal movement of the sections relative to each other.'

It is apparent that with the form-shown in Fig. bottom and will close together at the top, and that the strap fastening will etfectually lock the sections together. It is also apparent that each section may have one end vslptted and the other end plain, as a matter `portion resting on the top ot' said section,

and means for secining said sections together. Y

A culvert comprising a' pipe section having `slots in one end and' a mating pipe section having its end projected into said Islots with its lower portion resting onthe bottom of the first section and its 'upper desire to secure' IV, the pipe sections will nest at the y portion resting on the top of said section',

and a strap fixed to the circling the overlapping part of the secondN section to secure said sections together.

4. 'A culvert comprisinga .plpe section having one end cut out to receive a mating section, and an abutting section having its lirstsection and en-xV 5 4second section, and means for attaching the free end of said strap to theopposite side of said rst section. Y K

5. A culvert comprismg a pipe seetlon having one end cut away to recelve a mating section, a strap hinged to said first section adjacent to the edge of a. cut ont portion Copies of this patent may be obtained forve cents each, by addressing the Commissioner of Zlatients,l

lo secton,'a'mating section seated n said first e and encircling the mating section, an ear on said first section opposite thehinged mounting of Said strap, and an ear on said strap adapted to rest on and for attachment to said first named can-'for the purpose set forth.

.In testimony whereof I affix my signature in presence of two Witnesses.
